Current Construction Status
Frequently Asked Questions
How long will construction last?
- Construction is expected to last two seasons, from Spring 2018 to Fall 2019
What impacts can I expect?
- Plan ahead for night work seven days a week, with overnight lane closures on I-15.
- Residents and businesses adjacent to active construction can expect some increase in noise and dust.
- Drivers can expect the outside shoulder to be closed. Please use the inside shoulder or a signed pullout in case of emergency.
How much will the project cost?
- The project budget is $180 million, which includes costs related to the environmental study, design and construction. The project is state funded.
Who is the contractor?
- After a careful selection process, Ralph L. Wadsworth (RLW) was awarded the contract. They were selected based on best value competitive bidding process and because they proposed the fewest traffic impacts within the threshold set by UDOT.
- RLW is reducing traffic impacts by keeping all lanes on the freeway open during peak travel times.
How will this project help?
- Upon completion, this project will reduce delays by as much as 10 minutes on southbound I-15 from S.R. 201 to 12300 South in Salt Lake County
- The modifications to the I-15 interchange at I-215 will improve the movements from eastbound and westbound I-215 to southbound I-15 as well as rehabilitate aging bridges and address additional drainage needs.
- On 7200 South, the project will alleviate congestion between I-15 and Bingham Junction Boulevard in Midvale.
Why another I-15 project?
- Road improvements are implemented in sections as funding allows and as need dictates.
- Improvements to I-15 are part of a comprehensive, long-term plan to keep Utah moving along the Wasatch Front.
- I-15 is a critical part of our transportation system and experiences significant traffic congestion during peak travel times. The I-15 Southbound project will help manage traffic congestion and allow I-15 to function better with the surrounding transportation system.
- The I-15 Southbound project is the product of a well-coordinated, thoughtful planning process by Utah’s transportation agencies. This process includes growth projections and considerations for land use, transit, technology, connectivity between modes of travel and more through the year 2050. These agencies are actively studying transportation solutions beyond just increasing capacity and are working toward a future of multiple modes and options for getting around in addition to driving on I-15.
